Acoustic Guitar Watercolor QR Code for Stickers

About this design

An acoustic guitar with a long fretted neck sits at the center of a round badge, surrounded by treble clefs, staff lines and thin concentric sound-wave rings. The three finder squares are drawn as rounded brown and cream frames with square centers, set against the pale background. The guitar body and the scattered patches around it carry the modules as blotches of brown, ochre, black and cream. Strong dark-to-light contrast in those patches keeps the pattern readable, while loose gray and blue washes and ink splatters stay at the edges.
